I moved from cifs-utils 5.0 to 5.2. I didn't have keyutils installed and 
the compilation failed because configure checks for its presence, but 
doesn't abort if it's missing, and make tries to link to it.

Makefile.in:

@CONFIG_CIFSACL_TRUE@getcifsacl_LDADD = -lkeyutils $(WINB_LDADD)                
@CONFIG_CIFSACL_TRUE@setcifsacl_LDADD = -lkeyutils $(WINB_LDADD)

Apparently, getcifsacl and setcifsacl don't use keyutils at all, but 
cifs-utils links to it ?
